Fig. 8 shows flow chart according to an embodiment of the invention.With reference to figure 8, in box 810, terminal device 110 The event of such as cell reselection and/or tracing area change etc can be detected.In box 820, terminal device can determine institute Whether the event of detection is that tracing area changes.Change if event is tracing area, terminal device 110 can obtain system It accesses and sends TAU to cellular communication system and ask (box 830).Change if event is not tracing area, terminal device 110 can obtain system access and send location updating (for example, BE-TAU) request (box 840) to cellular communication system. After box 830, terminal device 110 can send position updating request (frame 842).It may be noted that system access is available, Because terminal device may send TAU requests in box 830.

In one embodiment, when terminal device 110 executes in same frequency layer or cell that different frequencies interlayer is found it Between cell reselection when, to selected cell execute for example about position updating process described in Fig. 4.

In one embodiment, network element 102 and/or local access node determine that the mobility of terminal device 110 is super Cross threshold value；And as the response to the determination, control message is sent to prevent terminal device 110 to be directed to terminal device 110 Cell reselection execution position update request in the cell (multiple) provided by network element 102 and/or local access node 112 (multiple).For example, network element 102 can use service identities (SI), mobility status estimation (MSE) and/or some other Estimate the means of speed of terminal equipment.For example, if terminal device 110 can be made with being moved higher than the speed of pedestrian's speed Prevent terminal device 110 from sending position updating request (multiple) with described method.In one example, if mobility State is " medium " and/or "high", then the position updating request that should suspend for sub-cell (such as sub-cell 114) is (more It is a).In one example, the mobility of terminal device 110 can be estimated by terminal device, and terminal device 110 then can To determine whether mobility is more than threshold value.Threshold value can be preconfigured to terminal device 110 and/or can be by cellular communication system (for example, network element 102) sends (that is, broadcast, dedicated signaling) and arrives terminal device 110.

Referring to there may be multiple sub-cells 176 in Fig. 5 B, such as cell 164.When terminal device 110 just in multiple sons it is small When being moved at least some of area 176 sub-cell, it may be beneficial to prevent 110 execution position renewal process of terminal device. In addition, multiple sub-cells 176 can have dormancy period, this indicates that they are switched on and off in turn.For example, dormancy period can be with It is controlled by network element 162.But since the quantity of position updating process increases, dormancy period may result in terminal device Battery consumption increases.Therefore, network element 162 and/or network element 102 can create sub-cell cluster, wherein when detecting When cell reselection in other sub-cells of sub-cell cluster, terminal device associated at least one sub-cell 110 can With not execution position renewal process.It may be thus possible, for example, to pass through by all sub-cells in the cluster of sub-cell and/or further Cell 164 sends paging message.

In one embodiment, Fig. 5 B are checked, may exist multiple sub-cells 176 in cell 164.For example, including In the microcellulor millimetre-wave attenuator for providing multiple access points of multiple sub-cells 176, for terminal device 120, to respectively More than one access point transmission position updating request (box 606) for providing one or more of multiple sub-cells 176 may It is beneficial.This potentially contributes to that position updating request transmission is avoided to be obscured by an obstacle, or works as and use multiple launching beams When, send position updating request using multiple wave beams.In addition, managing network element (such as the network element of multiple access points 162) multiple wave beams can be used to send location updating to terminal device 120 and receives (box 612).In one embodiment, net Network unit 102 realizes timer and/or counter by being directed to terminal device 110, limits triggered position updating process Rate.In another embodiment, terminal device 110 comes itself realization timer and/or counting by using the information of pre-configuration Device.For example, when terminal device 110 be located at specific sub-cell (multiple) it is interior when, timing to be used may be implemented in network element 102 Device.For example, timer and/or counter can prevent the execution position more than once in special time period of terminal device 110 Renewal process.For example, when terminal device 110 sends position updating request, network (for example, network element 102) can use Location updating receives to carry out response, wherein location updating receiving may include timer and/or counter information.For example, net Network unit 102 can not execute another location renewal process with requesting terminal equipment 110 in next 100 seconds.

In one embodiment, network element 102 is configured to execute following operation：It generates by least one office The sub-cell cluster that domain access node provides；Determine that terminal device is located in the sub-cell cluster；And to terminal device 110 Control message is sent, to prevent terminal device 110 from updating request for the cell reselection execution position in the cluster of sub-cell.

In one embodiment, terminal device is configured to execute following operation：It is received from cellular communication system Control message, control message requesting terminal equipment 110 stop for the cell reselection execution position at least one cell Update request；And it is based on the control message, it is limited in execution position update request at least one cell.

In one embodiment, compared with normal random access procedure, the position updating process is (for example, special random Access procedure) it is sent with lower-wattage.This for example may imply that compared with normal RAP, be at least used for the RAP of specific use with compared with Low power is sent.Therefore, special random access procedure (being used for cell level location updating) may not substantially interfere with just Normal random access procedure.

Above-mentioned solution may bring some benefits.It is possible, firstly, to be reduced by using the position updating process The size of terminal device tracing area.Therefore, with the cell level position that may not include terminal device 110 or other terminal devices The conventional tracing area set is compared, wherein needing the geographic area of call terminal equipment 110 can be smaller.

Secondly, this method can provide robustness and rollback solution.If position updating process failure is (for example, eventually The cell level Location-Unknown of end equipment 110), then terminal device 110 still can be located at larger tracing area based on TAU processes It is interior.

Third, the method proposed can be suitably used for the communication of MTC or IoT types, wherein the mobility very little of terminal device or not In the presence of.This is considered as an advantage, because the amount of IoT equipment is expected to very greatly, and may need optimization paging resource.I.e. Equipment tracking is set to remain unchanged, due to wireless or maintenance breaks, these equipment may need to change sub-cell.

4th, the method proposed can be minimized while better paging domain granularity is provided needed for for son The additional signaling of cell.

5th, the terminal device location information under the rank of sub-cell can be additionally useful for several purposes.For example, above and below user Literary information can be directly utilized in sub-cell, for example, the quick connection for towards sub-cell is established.Cellular communication system (for example, network element 102) can determine that user context information is stored in the duration in sub-cell and terminal device.It is another to show Example may be to promote the transformation of dormant cell state.In one case, if down link data can be used for its position sub small Known terminal device under area's rank, then cellular communication system (for example, network element 102) can be sent to the sub-cell " WAKE_UP " message (if the sub-cell is in a dormant state), for example passes through macrocell (for example, cell 104) during this period Simultaneously paging message is sent to the terminal device.In another case, network can be set by position updating process to terminal The standby associated sub-cell of identified frequent, and can be closed to frequent while down link data can be used for the terminal device Cell in the cell of connection in a dormant state sends " WAKE_UP " message.In addition, if terminal device selection macrocell is resident And the terminal device is known in the position of sub-cell rank, then cellular communication system can attempted to pass through the macrocell It, will be for the downlink transmission of terminal device to the sub-cell while incoming terminal equipment.
